Abstract
Graphene was used as the filler to mix with two kinds of polymer materials, poly(methyl methacrylate) (PMMA) and polypyrrole (PPy). PMMA is an insulator and PPy is an intrinsic semiconducting/conducting polymer. Graphene/PMMA nanocomposite (GrPMMA) was produced by solution blending and spin-coating deposition, and graphene/PPy nanocomposite (GrPPy) was produced by in situ polymerization and doctor-blade coating. The X-ray diffraction and Raman spectroscopy were used to characterize the structures of GrPMMA and GrPPy. The electrical conductivity was studied as a function of graphene concentration for both GrPMMA and GrPPy. The electrical conductivity of PMMA was improved drastically after adding graphene, and the electrical conductivity of GrPMMA increases as the graphene concentration increases. However, the electrical conductivity of PPy decreases after adding graphene, and the electrical conductivity of GrPPy decreases as the graphene concentration increases. The difference in change in electrical conductivity of PMMA and PPy after addition of graphene may be due to the different electron transport mechanisms of those two nanocomposite materials.
